Benefits of technology

[0008] Another object of this invention is to provide a concealed door closer which is relatively simple in construction, positive in operation and relatively inexpensive to fabricate.

Problems solved by technology

However, wherever such door closers are externally connected between the door and the associated door frame, their presence is always quite visible and unsightly.
It has also been noted that with such door closers, it often happens that one's clothing may also become entangled with the door closer.
While efforts have been made to obviate the problems encountered with the conventional externally and visibly connected door closers, such known efforts entailed excessive costs and installation difficulties.
Even with the currently known door closers of the so-called concealed type, a considerable portion of the operating mechanism remains readily noticeable and unsightly.
However, with such known floor, ceiling or frame located closers, the actuating levers or connecting mechanism associated with the floor or ceiling mounted piston and cylinder assembly of the door closer would still be visible and unsightly.
Further, such floor, ceiling or door frame attempts to hide the closer assembly presented substantial installation difficulties, as is readily evident, and which installation difficulties become greatly aggravated for the after marketed installations of such closers.

Embodiment Construction

[0020] Referring to the drawings, there is illustrated in FIG. 1 a door 20, a door frame 21 and linear assembly 22 wholly concealed within the associated door 20. As used herein, a linear assembly is defined as a door closer or a door closing speed controlling device that includes a cylinder having a reciprocally mounted piston and a piston rod connected thereto which extends through one end of the cylinder. It will be understood that the structure of the door 20 may take any suitable form. Such doors 20 may comprise opposed longitudinal support frame 20A, 20B to which the side door panels 20C and 20D are secured to define a hollow type door. In the event of a solid door (not shown), the instant invention would require that such solid door have formed therein a chamber such as shown at 23, sized to receive the linear assembly 22. In the illustrated embodiment of FIG. 1, two such linear assemblies are illustrated, one being concealed adjacent the top of the door 20 and the other conc...

Abstract

A door assembly and a door closer arranged and constructed so as to be wholly concealed within the associated door, yet is rendered readily accessible to effect the adjustment thereof to regulate or control the closing speed of the associated door. The door closer is capable of performing all of the functions expected of a door closer such as controlling the closing force, regulating the door closing speed and the arresting of the door in a predetermined opened position.

Description

RELATED APPLICATION [0001] This application is a continuation application of application Ser. No. 10 / 807,021 filed Mar. 23, 2004, entitled Door Assembly With Concealed Door Closer.FIELD OF THE INVENTION [0002] This invention is directed in general to door assembly, and more specifically to a door assembly with a concealed closer within the associated door. BACKGROUND OF THE INVENTION [0003] Door closers are commonly used on doors for effecting the closing of a door upon the release of the door on opening. Such door closers are externally connected between the door and the associated door frame. Generally, the door closers are connected to the door and associated frame about midway between the top and bottom of the door. Oftentimes, the closer is connected either adjacent the top or bottom of the door. However, wherever such door closers are externally connected between the door and the associated door frame, their presence is always quite visible and unsightly. It has also been note...
